Ryan Seacrest Is No. 1 on THR's Reality Power List

From Fox’s Hell’s Kitchen to G4’s American Ninja Warrior to Oxygen’s upcoming Paris Hilton project, Arthur Smith’s slate isn’t lacking in diversity. “We’re all over the place, but in a good way,” says the Canada native who got his start in front of the camera doing films, sitcoms and voice-over work as a young adult. (Listen closely and you’ll hear him doing voice-overs on his Kitchen spinoff, Kitchen Nightmares.) Proof of his colorful portfolio crystallized three years ago when Smith walked into his San Fernando Valley-based production office and was greeted by designers from TLC’s Trading Spaces, fighters from Spike’s UFC Countdown and “gangstas” from BET’s American Gangster. Diversification is paying off: Hell’s Kitchen has been the No. 1 broadcast show for four summers running; Kitchen Nightmares has lifted Fox’s Friday night average by 150 percent. With his producing partner Kent Weed, they’ve sold eight pilots since November.
